Hello,

I am creating my first module with DotNetNuke 4.8.0 Starter Kit and C#. Its name is "MMNoticias", The first screen works fine. I have add a

new user control called "Categorias.ascx". This is how I call it from ViewMMNoticias.ascx.cs:

 ModuleController objModules = new ModuleController();
 Response.Redirect(Globals.NavigateURL(PortalSettings.ActiveTab.TabID, "Categorias", "mid=" + ModuleId.ToString()));

Things don't work out well when the other user control is called by the code above after I clicked on a LinkButton.

I get differents error messages according my login type:

-If am logged as host:

Error: Cadastro de Categorias is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Unable to cast object of type 'ASP.desktopmodules_mmnoticias_categorias_ascx' to type

-If am logged as Administrartor:

If I am anonyms:

Module Load Warning

problem persists, please let the Site Administrator know.

I don´t know why it doesn't works out well. What is the problem?

Thanks in advance,

Kau.

ps: MM Noticias = MM News; Categorias = Categories; Cadastro de Categorias = Categories Cadastre;
